Abstract
Description
- The invention pertains to roll-type paper products such as paper towels and toilet tissue which comprise lengths of a paper web which are wound onto disposable paper or cardboard cores; and which lengths of paper are conventionally subdivided into convenient sheets by transverse lines of perforations or slits. Such paper is generally high bulk by virtue of, for example, low density paper making methods, and/or by embossing. Thus, in addition to the void space within the conventional hollow cores, such papers have high void volumes. Accordingly, the present invention provides compact, core-wound paper products and methods of making such products having substantially reduced shipping and storage volumes.
- A Package Of Compressed Resilient Articles and Concomitant Method of Unpackaging is disclosed in U. S. Patent 4,595,093 which issued June 17, 1986 to Joseph H. Eckstein. The figures depict the compressed articles as being cylindrical shaped and having circular tubular cores. The exemplary embodiment is stated to have been compressed to reduce the volume of the array of articles (eg, rolls of toilet tissue) reduced by about twelve percent.
- A Process of Packaging Batts of Fibers is disclosed in U.S. Patent 3,537,226 which issued November 3,1970 to Martin D Le Van et al. This discloses forming a wound batt or roll on a rigid core; removing the core; encasing the roll in an air impervious bag, evacuating air; and securing the contracted structure with a wrapper of sufficient tensile strength to main substantially the contracted state. As shown in the figures, there is a void in the centre of the complete package which has an oval cross section.
- A Method of Baling Fibrous Material and Bale is disclosed in U.S. Patent 864,975 which issued September 3, 1907 to Luce. This discloses flattening cylindrical bales of cotton which were formed on a mandrel, and removed from the mandrel before being flattened. Thus, they are coreless, annular bales. The apparatus includes means for tying the flattened bales together in pairs to provide duplex bales.
- A Multi-Roll Package of Compressible Materials is disclosed in U.S. Patent 4,444,311 which issued April 24, 1984 to Rias. This discloses a package which comprises compressible rolls, contoured panels having V-shape troughs, and bindings for securing the rolls and panels into a somewhat compressed orthongonal array. The invention is said to apply in particular to the packaging of fibrous insulating material such as insulating rolls which are subjected to limited compression in order to avoid permanent deformation.
- A paper product comprising at least two compression loaded, core-wound rolls of paper and compression constraining means, said rolls of paper comprising a core and a length of paper wound thereon, said cores being substantially flat and said rolls having flattened sides, said rolls being susceptible to being shaped by a user so that said rolls have a generally round cross section and so that said cores have an open tubular shape, wherein the rolls are placed such that the flattened sides of the at least two rolls are contiguous, the compression constraining means comprising an enclosure about the at least two rolls is known from GB-A-709 363.
- A paper product in accordance with the invention is characterised in that the compression constraining means further comprises a constraining band about each roll or about the at least two rolls, the enclosure being flexible.
- In accordance with one aspect of the present invention, a paper product is provided which comprises a unidirectionally compression loaded, core-wound roll of paper and compression constraining means in which the roll of paper comprises a core and a length a paper wound thereon, and in which product the core is substantially flat and the product has a somewhat obround shape. The product is susceptible to being shaped by a user so that the product has a generally round cross section and so that the core has an open tubular shape.
- According to the invention, plural such rolls are disposed and constrained in a predetermined array. For example, a linear array of four rolls having their flattened cores in parallel relation. In such embodiments, the constraining means may comprise an array band and a flexible enclosure, and may further comprises bands about the individual rolls of the array. In a method aspect of the invention, a core-wound paper product such as a roll of toilet tissue or a roll of paper towels is subjected to a unidirectional compressive loading of sufficient magnitude to cause the core to be substantially flattened. The constraining means are then secured while the roll is still compressively loaded; and then the compressive loading is relieved. According to a method aspect of the invention, more compressive loading is applied than required to flatten the core in order to achieve greater compaction prior to securing the constraining means, such more compressive loading being partially relieved prior to securing the constraining means. Preferably, such partial relieving is to the level at which the core of the product would commence to open if the loading were to be further relieved.
- While the specification concludes with claims which particularly point out and distinctly claim the subject matter regarded as forming the present invention, it is believed the invention will be better understood form the following description taken in conjunction with the accompanying drawings in which identical features in the several views are identically designated and in which:
- Figure 1 is a perspective view of a paper product which embodies the present invention, and in which view some of the elements have been partially torn away to more clearly show the underlying elements.
- Figure 2 is a perspective view of a core-wound, contemporary paper product such as a roll of toilet tissue paper having a cylindrical shape, and which includes a hollow tubular core having a circular cross section.
- Figure 3 is a perspective view of the article of Figure 2 after it has been subjected to a sufficient unidirectional compressive force to flatten its core, and after a constraining band has been secured about the flattened roll in accordance with the present invention.
- Figure 4 is a graph which illustrates the reduction of the minor diametral dimensions of both the overall roll and the core as a roll of contemporary paper towels was subjected to a progressively increasing, unidirectional compressive loading.
- Figure 5 is a graph which is similar to Figure 5 except the roll of paper towels was subjected to a lesser maximum compressive loading; and curves are shown for both progressively increasing the loading, and progressively relieving the compressive loading. This illustrates the compressive hysteresis of such conventional paper towels.
- An exemplary embodiment of the present invention is shown in Figure 1 to be a
paper product 20 comprising a linear array of fourflattened rolls 21 of paper,flattened cores 22 only one of which is visible in Figure 1, aroll band 24 about eachroll 21, anarray band 26 about the array of fourrolls 21, and atransparent enclosure 28 such as a wrapper or bag of sheet material. In order to clearly shown the various element ofpaper product 20, a portion ofenclosure 28 has been torn away leaving atorn edge 30; a portion of thearray band 26 has been torn away leavingtorn edges band 24 about oneroll 21 has been torn away leavingtorn edges - An
unflattened roll 21 of core-wound paper is shown in Figure 2 to have a cylindrical shape, and atubular core 22. The free edge of thefirst sheet 41 is designatedfree edge 40, and a line ofperforations 41 is shown which demarks thefirst sheet 42 from thesecond sheet 42. Such lines of perforations are provided at sheet length intervals to facilitate tearing individual sheets from the roll. - Figure 3 illustrates a
roll 21 of core-wound paper after it has been subjected to sufficient unilateral compressive loading toflatten core 22, and giveroll 21 an obround shape; and after a constrainingband 24 has been applied. The function of the constrainingband 24 is to prevent substantial expansion of theroll 21 due to its inherent resilience until the constrainingband 24 is removed as by a consumer. For convenience, the banded roll illustrated in Figure 3 is designatedbanded roll product 45. Thus, while not wishing to clutter Figure 1 with unnecessary designators, suffice it to say thatpaper product 20 as shown consists of fourbanded roll products 45. - An
exemplary roll 21 of paper towels was used to obtain the test data which are embodied in the curves of Figures 4 and 5. The roll had a diameter of 5.25 inches (about 13.3 centimeters), and a length of 11 inches (about 28 centimeters). The core was a wound paper core having a diameter of about 1.625 inches (about 4.1 centimeters). The paper toweling had a basis weight of about 28 pounds per 3000 square feet (about 45.6 grams per square meter); and a density of about 0.09 grams per cc. The paper toweling consisted of two plies which had been embossed. While numerical data was obtained, and is discussed below and used to plot the curves in the graphs Figures 4 and 5, it is not intended to thereby limit the present invention to such numerical values or levels or ranges. Rather, the qualitative nature of the data are believed to be more significant with respect to understanding and practicing the present invention. Additionally, albeit the representative data were obtained through the use of a sample roll of paper towels having stated dimensions, weights and densities, and which paper was embossed, it is not intended to thereby limit the present invention to those values or characteristics. - The compressive loading referred to herein was obtained by placing a
roll 21 of paper product on a flat, horizontal anvil plate with the axis of the cylindrical-shape roll extending horizontally. Strips of banding material were positioned under the roll and across the roll to enable banding the roll while it was still under compressive loading. A horizontal pressure plate was then pressure actuated downwardly to apply the compressive loading. During compressive loading, the roll was unconstrained horizontally. With this orientation, the distance between the anvil plate and the pressure plate is hereinafter referred to as the thickness of theroll 21; and it is alternatively referred to as the minor diametral dimension of the roll: that is, it is the diametral dimension of the roll which is reduced during compressive loading. - Referring now to Figure 4, it is a graph on which
curve 50 shows the relationship between the minor diametral dimension of aroll 21, Figure 2, as it is subjected to a progressively increasing compressive loading; andcurve 51 shows the concomitant relationship between the minor diametral dimension ofcore 22. These data were obtained using a roll of Bounty (registered trademark of The Procter & Gamble Company) paper towels. However, without wishing to thereby limit the present invention, it is believed that the character of the curves is more indicative of the benefits derived from the present invention than the absolute loadings and dimensions. For example,curve 51 indicates that the core has fully collapsed at a loading of about 60 pounds (about 27 kilograms); and that substantially more compaction was available upon increasing the loading on up to 940 pounds (about 427 kilograms). - Figure 5 is a graph which illustrates the compressive hysteresis of both a
roll 21 and acore 22, Figure 2.Curve 61 is forroll 21 as compressive loading was increased, andcurve 62 is forroll 21 as compressive loading was decreased. Similarly,curve 63 is forcore 22 as compressive loading on theroll 21 increased; andcurve 64 is forcore 22 as compressive loading was progressively decreased. From these curves it is apparent that as compressive loading is increased up to about 200 pounds (about 91 kilograms), and then decreased to about 40 pounds (about 18 kilograms), the core remains substantially flat, and the final minor diametral dimension ofroll 21 is about 2.25 inches (about 5.72 centimeters) whereas, when the progressive increase of compressive loading is stopped at 40 pounds (about 18 kilograms), the final minor diametral dimension ofroll 21 is 3.25 inches (about 8.26 centimeters). Thus, loading on up to 200 and then backing off or relieving to 40 pounds (about 18 kilograms) and then banding results in a banded thickness of bandedroll product 45 of about 30.7 percent less than if simply loaded to 40 pounds (about 18 kilograms) and then banded. However, it is also clear that simply loading aroll 21 up to about 40 pounds (about 18 kilograms) and then banding while holding that level of loading results in a reduction of its thickness of about 38 percent from the original thickness/diameter ofroll 21. - From the foregoing, it is clear that substantial thickness reductions and concomitant volume reductions are available from simply compressively loading a
roll 21 up to the level that causes the core to become substantially flat and banding the roll while it is so loaded; that further substantial thickness decreases and concomitant volume decreases are available thru applying higher levels of compressive loading and banding while the roll is loaded at the maximum applied loading; and that constraining forces can be substantially reduced without proportional increases in thickness and volume if the loading on the roll is relieved somewhat from its maximum value. For example, to the level at which the core would commence to open. - Alternative embodiments of the present invention, not illustrated in the figures, include embodiments similar to that shown in Figure 1 except either the enclosure or the array band may be omitted, and the individual roll bands may be omitted. However, the most preferred embodiment at the present time comprises an enclosure of transparent polyethylene film, and individually banded rolls.
- While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
